Title: Treatment of tannery waste to give chromium sulphate and proteins
Inventor: GUARDINI GIULIANO
IPC: A23J/
Filed: 1982-02-02
Granted: 1987-02-25
Abstract: Chromium and proteins are extracted from tannery waste by the following process: the waste is mechanically broken down and treated with alkali to effect hydrolysis, iron filings are partially sepd., the alkaline suspension is filtered under vacuum to separate soluble polypeptides from insoluble chromium hydroxide, and these are purified separately. The polypeptides give high purity proteins and the chromium is obtd. as basic chromium sulphate suitable for use in tanning. Specifically the physical breakdown of tannery waste gives a prod. of millimetric size, and this is treated with Na, K, or Ca hydroxides, pref. at pH 11-12.5 and at a temp. of 95 deg.C or above, for a few minutes. Iron filings and abrasive sand, used in the tanning process, are allowed to settle, and the liq. decanted. This liq. is then filtered to give a chromium hydroxide residue and a filtrate contg. soluble proteins. The process overcomes the difficulties of disposing of tannery waste. The proteins may be used in animal feeds, foliar fertilisers, cosmetics, and for industrial use generally.

Granted: 1994-05-24
Abstract: The invention discloses a bushing suited to insure the mechanical sealing between a pipe and a connecting body belonging to a plumbing installation, which comprises an elastic ring (2, 30, 45, 61, 71, 81, 91) suited to receive in its interior a pipe and to block it mechanically, and an annular element (5, 22, 52, 75, 85, 98) with an inner surf ace which is suited to insure the water sealing of the pipe which it receives and with an outer surface having such a profile as to insure the water sealing of the body connecting it with the bushing. The ring and the annular element are rigidly and intimately united with each other, so as to form a single piece. Moreover, the elastic ring presents an inner rough surface suited to be sealed on the outer surface of the pipe and an outer surface with a section of profile in the shape of a truncated cone, which transmits the axial component exerted by the sealing force between the bushing and the connecting body. <IMAGE>

Title: Triple partition construction with sound insulation
Inventor: STAUSKIS VYTAUTAS JONAS
IPC: E04B2/00
Filed: 2005-03-16
Abstract: The invention relates to a partition construction that comprises a triple partition made of different blocks and used for increasing a sound insulation between flats without increasing thickness of the partition and wall weight per unit of the area. The partition may be used in the construction of residential and office buildings. The triple partition consists of two walls of deferent thickness and density materials, an air space, in which is built a single wall formed from two boards between which a bearing element and an insulation material are disposed, or a single insulating partition, both the single wall and the single insulating partition are unbound with the massive walls and thus the walls constitute an additional sound insulation construction which gives an additional insulation at the same thickness of the triple partition.

Title: Method and device for the spectroscopic imaging of the object
Inventor: KAŠALYNAS Irmantas
IPC: G01J3/00
Filed: 2014-12-05
Abstract: The invention describes the measurement and simulation of the images at terahertz frequency range of electromagnetic spectrum that can be used for the detection and identification of the concealed objects. The method proposes to split the amplitude-modulated terahertz radiation into two coherent light beams in order to increase the contrast of the image. The first beam is directed to different position of the test object; all transmitted or reflected THz radiation is collected on the beam splitter and combined with the second beam in order to have interference of both beams. Incoherent terahertz detector measures the intensity of the interference that is dependent on electromagnetic field amplitude and phase both modified by the object physical parameters. The detector signal dependence on the position is used to create the terahertz image of the object.

Patent MX-172698-B (MX)
Inventor: FREEBURG THOMAS A
IPC: H04L12/64
Filed: 1990-09-05
Abstract: A network interface architecture for a packet/fast packet switch is described. This architecture provides for the combination of both voice and data in a single switch using a common packet structure. It allows for the dynamic allocation of bandwidth based on system loading. This includes not only bandwidth within the voice or data areas of the frame, but also between the voice and data portions. The network interface (105) provides a means (101) of passing all packets through the Network Interface (105) or allowing the packet devices to directly transfer packets between one another. The bandwidth allocation can easily be changed because the control and data memories are synchronized to one another. The architecture allows for the data packets and the control of bandwidth allocation to be controlled by a single switching device. It synchronizes the transfer of the data and the allocation of bus bandwidth. The control of the packet devices can be controlled at a very high bit rate such as 40 Mbps. It allows packet devices to directly transfer packets. It allows for easy re-allocation of bandwidth through the use of the NI Base Registers.
